<p>Hi <span class="user-group-mention" data-user-group-id="1380">@WG-rustc-dev-guide</span> ! We will have our meeting in ~12min.</p>
<p>The current agenda:</p>
<ul>
<li>Updating getting started/building/debugging resources... there seems to have been a lot of activity in this area recently</li>
<li>Finding reviewers for the open PRs on the rustc-dev-guide</li>
<li>Looking at the reorg of the guide</li>
</ul>

<p>So, to elaborate a bit more on the first point:</p>
<ul>
<li>We merged the getting-started guide, but there are still a bunch of improvements/corrections that could be made.<br>
    - e.g. <a href="https://github.com/rust-lang/rustc-dev-guide/pull/792">https://github.com/rust-lang/rustc-dev-guide/pull/792</a></li>
<li>There are also some changes in the pipeline to the x.py defaults that will require updating a bunch of things (I think <span class="user-mention" data-user-id="232545">@Joshua Nelson</span> was planning to do these updates?)<br>
    - MCP: <a href="https://github.com/rust-lang/compiler-team/issues/326">https://github.com/rust-lang/compiler-team/issues/326</a></li>
<li>There is discussion around what the best <code>config.toml</code> recommendations are.<br>
    - This is in the MCP above, as well as zulip in various places and in <a href="https://github.com/rust-lang/rustc-dev-guide/pull/795">https://github.com/rust-lang/rustc-dev-guide/pull/795</a></li>
</ul>
